I've had plenty of problems with M*'s portfolios not updating timely, sometimes even for a few days. Today the price of IVV on my laptop and iPad are both the same, both updated but the change is different. My laptop says down $0.74, which I believe is correct, while the iPad app says down $0.59. As far as I can tell there's no dividends or any other reason for the difference. For all the crazy data problems M* has, this one is new for me.
